PROCESS 0F PREPARING LINSEED, &c., FOR PRESSING IN EXTRACTING- OILS.

\ Speccationof Letters Patent No, 15,594, dated August 19, 18156.

To @ZZ whom it concern: j

Be it known that I, CHARLES MOORE, of Trenton, in the county of Mercerand State of New Jersey, have invented certain new and usefulImprovements in the Process of Extracting Oil or other Liquids from thePulp or Prepared Linseed or other Seeds and other Substances; and I dohereby declare that the same are described and represented in thefollowing specifications and drawing.

To enable others skilled in the art to use my improvements I willproceed to describe the construction and operation of a machine forperforming the process referring to the drawings in which the sameletters indicate like parts in each of the figures.

Figure l, is an isometrical view of a press. Fig. 2 is an isometricalView of the mold. Fig. 3 is an isometrical view of the former. Fig. 4 isan isometrical view of the strick.

The nature of my improvement consists in pressing or packing the pulp ofprepared linseed, or other seeds or other substances, into cakes bypressing the pulp or other substance into a mold prepared for thepurpose, taking care not to press it so hard as to force out the oil;but merely pack it into a cake and make it occupy a smaller space, so asto put more or double the quantity into a press of a given size, andpress it at a single operation, without materially increasing the powerrequired to operate the press, or prolonging the time required toperform the pressing. j

By molding and packing the pulp as above mentioned, I can substitutecotton sail duck for the knit woolen bags so as to save seventy-five percent. of the cost of bags; and dispense with the leather usually placedbetween the bags entirely so as to save the entire cost of it.

In the accompanying drawings A, is the bottom of a press withcleats B Bat each end between which cleats the mold O, Fig. 2, is placed when itis to be filled with the material to be packed. The bottom A, issupported upon two standards D, D, which standards are perforated forthe journals of the `shaft E, which turns freely in them. There is acrank fastened to each end of the shaft E, just outside of the journals:one of these cranks is seen at F, embraced by the link Gr, whichconnects it to the head or follower L, of the press by means of thestaple H, which allows it to vibrate, so as to adapt itself in pressing,the vibration being limited when it is not pressing by the pins fastenedin the head for that-purpose one of which is represented at I. Thebracket J, is fastened to.the bottom A, to support the head L, in theposition represented in the drawing. The hopper M, is made in the formrepresented and fastened to the bottom A by the hinges N, N, so that itmay be raised to put in or take out the mold O, Fig. 2. The interior ofthis mold is made to correspond in size with the interior of the hopper`M. One end of the mold O, is made a little wider Vthan the other andleftopen, so that the cake pressed in it will slip out of the moldreadily when the mold is put in the press, which is to press the oil, orother fluid out Vof the cake formed in the mold. The forming board P,Fig. 3, is made a little smaller than the interior of the mo-ld O toform the cloth, when a cloth is used on the cake packed in the press.The Strick Q, is made to fit the top of the hopper M and is used tolevel the pulp and to strike off the surplus. The frame R, is fastenedto the bottom A to guide the link and head as it is brought over thehopper. The stop S, is fastened to the head L, to aid in guiding it intothe hopper M, as it is brought down by vibrating the lever T, fastenedto the Mend of the shaft E. When the mold O, is put on the bottom A, theopen end of the mold is closed whileit remains in the press, by one ofthe cleats B, so as to form the cake packed.

The press having been constructed as above described, the mold O is puton the bottom A and one end of a piece of sail duck (or other suitablecloth which is a little wider than the mold and twice as long) is spreadover the mold O, so that one end of the cloth will be even with theright hand or closed end of the mold, and the hopper M shut down uponit, and the cloth pressed into the mold by the former P,

which is removed from the mold and the hopper and mold lled with pulp,which is spread and leveled by the strick Q5, and the surplus `pulpstruck off at one end into a trouglf or other receptacle by the strick,which is made to fit between the cleats, U, U, 0n the hopper. The headM, is now brought over the hopper and the lever T is vibrated so as toforce the projection V on the under side of the head down into thehopper, so as to press the pulp into the mold and `make a compact cake,but it should not be pressed so hard as to express, or force out any oilor other fluid that may be .in the pulp, or other material that may beworked into cakes preparatory to being pressed. The head should now beraised and pushed back, and the hopper turned up, and the loose end ofthe cloth spread over the cake, so as to cover it entirely, when thecake formed may be carried upon the mold, and laid in a press, when themold may be drawn out leaving the cake to be operated upon by the presswhich is to express the oil from the cake.

The advantages of the above mentioned process may be enumerated asfollows: 1st, the subsequent pressing of a given quant-ity of materialis performed in half the timesaving one half the labor and expense ofpresses, to perform the subsequent pressing: 2nd, one man cany make thecakes, or prepare double the quantity of pulp for the press which is toextract the oil in the same time, thereby saving one-half the labor;3rd, there is more oil obtained from the pulp or material pressed, asthe cakes are uniform in thickness and compactness therefore they arepressed cleaner than when prepared in the old way, in which the materialwas unevenly spread, and the thick parts prevented the thin from beingpressed clean; 4th, the cotton canvas used by the new process costs onlyone fourth as much as the knit woolen bags heretofore used; 5th, asthere is no leather required to be placed between the hair pads andplates therefore the entire cost of the leatheris saved.

In performing the above described process, I do not intend to limitmyself to the press or packing machine described, but to use such otherkinds as will answer the purpose; and there may be substances which canbe packed without a cloth.

I believe that I have described the process which I have invented and anapparatus by which it may be performed so as to enable any personskilled in the art to use the same. I will now specify what I desire tosecure by Letters Patent, viz.

What I claim as my invention and improvenient in the process ofextracting oil or other liquids, from the pulp of ground or preparedlinseed or other seeds, or other substances, is-

Forming it or them into cakes by molding and partially pressing orpacking it or them substantially as described for the purposes setforth.
